Decades of research document that children learn more when their instruction is systematic, explicit, and efficient. Effective instruction is accelerated instruction, with students learning more within a shorter period of time. Siegfried Engelmann and Wesley Becker, the founders of Direct Instruction, pioneered the research in explicit instructional techniques. All of the Direct Instruction curricula are based on the elements that they and their followers derived through years of careful research.
Even though many curricula include elements of effective instructional programs, this does not mean that they are necessarily effective. Specialists in the field distinguish Direct Instruction (capitalized), the programs developed by Engelmann and his colleagues, from direct instruction (no capitals), curricula that incorporate only some of the effective elements.

An article by Cheryl Schieffer and colleagues, published in 2002, analyses DI’s Reading Mastery program and shows how it embodies the elements of effective instruction. [Schieffer et al, JODI, vol. 2, no. 2, pp. 87-119]
DI Programs are based on years of research on how children learn and the most effective ways to teach. This work produced the basic principles of effective instruction: All children can learn when instruction is systematic, explicit, and efficient. Poor achievement does not result from poor students, but from poor teaching. Direct Instruction programs, developed by Siegfried Engelmann and colleagues, incorporate all of these elements of effective instruction.
Many studies have evaluated Direct Instruction programs and documented their effectiveness. NIFDI's searchable database includes summaries of dozens of peer reviewed, scientifically strong studies of DI programs. See The DI Research Base and Search for Articles on DI.
All Direct Instruction programs are extensively field tested during development. Students and teachers throughout the country try out each program, and their feedback is used to make sure they are highly effective. See Field Testing DI Programs.
